' o WW? TEE-fins A EUPFTLIE'I 'IENTAB F515 VELEZCLE' To 0M '21: lw-m mogroorwarn lie it known tliatzlg (luvs Hesmzvos, a citizen of the United Estates iresiciizig at .itvliison, in the county of :Tltchison and P lie at Kansas, have invented new and useimprovements in Supplemental Tires tol/ohiole-= fl heels, of which the following is a specification.

My invention relates to supplementai tires for vehicle wheels, more particularly to such are. furnisood with pneum wh reby the vehicle, such as an :ooile, um. reaoily changeol from its ptatiozi to ordinary roacl use and made applicable for use upon the rails of a railroad track.

The in obi if my invention is to pro- \ide metal flanged tires so constructed to enable a railroad o'f icial, or other person, to attach the same quickly and securely to the vehicle wheels, and after the run on the track has been made to permit of the removal of the metallic flanged tires so as to allow the automobile to continue its way over ordinaiy roacis.

With this and. other objects in View. the invention consists in the construction. cosy bination. and arrangement. of parts hereinafter fully described, and illustrate-in the accompanying drawing, it beisfig' understood that valious changes in form, proportions and minor details may be made within the scope of the invention.

accompanying drawing, iioi'm part of specification, E are, respec "1y, anal edge views o 3 4% are ateriel made in one '5,

r ciescribed, being The tread, surface of this annular continuous flange 2 for men: v the si le of the rail, and a part 3., the surface or tread oi" which adapted the top of the rail. Upon the inoei sm'i ace of the annular flanged member 1 are a pair of grooves 4: running continuously around it. @ne of the grooves is pie erably pissed directly over he shown, While the other groove is pa and substantially in close proximity to its companion groove. The inner Walls of the grooves 4 are inclined, as shown at 5. for a purpose hereinafter explained.

6 ami 7 are rigid annular members, the

inner surface of? each being curved as shown by 6 ofi'i' so that when these two annular members are broughttogetiiier. as in rig. they will fit the tread and parts of the sides of the inflated tire. The outside of each member 6 and '4 is provided with a tongue 8 0r 8*, the inner side of each tongue heing inclineri as at. 9.

In the use of supplemental. tire the members 6 and T! are placed around the infiatable tire A, preferably when the latter is in a somewhat deflated condition. By means of the tongues 8, 8 and grooves 4., 4- the members 6,? held upon the annular member 1. The angularit-y of the tongues 8, 8 as shown at 9 and the corresponding angularity of he grooves 4 asst .5, permit of an. easy of the tongue and groove connection. The tire. may now be fully inflated when she curves sin-faces i and. 7" will a compiete holciing seat for tire.

After the sectional members 6 and 7 have been placed upon the tire and. upon the annular member 1, they are forced apart by means of screws M which pass through lugs 13 of one member and fest upon the lugs 12- of the other member, as shown in Fig. 1. Thus it, will be seen that the annular member 1, with its tread surface and flange. and the sectional members 6 and 7 serve to make a strong composite rigid tire for automobile wheels adapted for use upon. ro'lroaci rails. Preferably members (i an? I are each composed of two sections,
